INTERNAL-COMBUSTION MOTOR.

Application led January 11, 1915. Serial No.i1,49l1.

To @ZZ whom t may concern.'

Be it known that I, DANIEL MnnANr-GH, a citize'n of the United States, and a resident of Buechel, county of Jeiierson, and State of Kentucky, have invented a certain new and useful. Improvement in Internal-Combustion Motors, of which the following is a speeilication.

This invention has reference to internal combustion motors and relates especially to improved means of delivering motive Huid to the working cylinder dispensing with the usual carbureter.

A further object is the provision of means for varying the amount of motive fluid delivered.

The invention may be understood from a consideration of the following detailed description, taken in connection with the acl companying drawing, which forms a part of this specification, with the understanding, however, that while the drawing shows a practical embodiment of the invention, the latter by no means limits me toany exact conformity therewith but may be embodied in any other forms which come within the scope of the claims appended hereunto.

ln the drawing wherein similar reference characters designate like parts; Figure 1, is a transverse sectional view of a portion of a motor with parts in elevation; Fig. 2, a side elevation of the portion shown in Fig. 1; Fig. 3, a modification of the pump actuating means; Fig. 4, an elevation, partly in section of the spray head; Fig. 5, a view showing the application of a centrifugal governor to control the stroke'of the fluid delivery pump.

Referring to the drawing *1* designates a cylinder within whichva piston *2* of the usual construction operates. A suitable valve casing *3*, having communication with an inlet port *lis iitted in the cylinder head. The casing 3, is provided on its lower end with a valve vseat *5* on which a valve *6* closes, an elongated stem *7* extends upward from the valve, passes through the center of the casing, and has an annular collar *8* near its upper end. A coil spring *9* coniined between the collar and the casing serves to close the valve 6. The valve is operated by means of a rocker arm *10* pivotally supported centrally at the upper end of a standard *ll*. To the outer end of the rocker arm a rod *l2 is pivotally connected and de` pends to engagement with suitable operating means such as a cam *13* secured on a shaft *14* A valve chest *15* hav ingan exhaust outlet *16* in the upper end thereof is formed with an internal annular seat *17* against which a piston valve *18* closes, and col'nmunieatce with the cylinder l by means of a channel *19*. A rod *20* depends from the valve 18 to engagement with suitable operating means, such as a cam*21* secured on a shaft *22*. An exhaust tube, or pipe, *2B* extends from the outlet 16 through the inlet port 4 and is provided on its outer end with suitable connecting means, such as a flange *24*. On the outer end of the inlet port 4 there is Secured an air inlet valve *25* which comprises a casing *26* having an opening *27* in its outer end, a bridge bar *28* spanning said opening, a valve stem *29* passing centrally through said bar, a valve head *30* on the inner end of said stem adapted to close the opening 27, an adjusting nut *31* on the outer end of the stem, anda coil spring *32* confined between the nut and the bar which serves to close the valve head on the opening 27. A pump *85*, preferably of the diaphragm variety, suitably positioned for actuation by the motor serves to deliver fuel thereto. A supply pipe *36* leads from a suitable source of fuel supply to an inlet *37* of the pump. A delivery pipe *39* leads from an outlet *38* of the pump to a three Way valve *40*. From the valve 40, the delivery pipe branches, one branch *42* terminating within the inlet port 4 where it is provided with a spray head *43*.` A spray head of any suitable construction may be employed, as illustrated it comprises a shield, or abutment, *44* disposed on the end of the pipe, opposite the outlet therefrom, at such an angle that the iuid from the pipe will imp nge thereon and be nebulized and delected thereby. The spray head is so positioned that the spray therefrom will strike against the exhaust pipe 23 and be vaporized by the heat thereof. The other branch *45* of the delivery pipe leads from the valve 40 to a connection with a spray plug *46* inserited in the side oi the cylinder in such a position that the spray therefrom will be directed on the head oi' the piston.

The pump comprises a suhstantially cup shaped body portion 5lwithin which, on an annular leiilg'e M53-, .a diaphragm -5/lis clamped hy means of a screw threaded retainingring A striker pin 56- is Centrally positioned on the diapliragm to receive the impulses from the operating' mechanism. The pump is secured by suitable means on a plate, or hair il. transmission element h-6O is provided which comprises upper and lower arms 62, G3- arranged in angular relationship on and extending in parallel contipguous planes from one side/of a. shaft -6l--, and a coil spring -GG- interposed between the outer ends of said arms; the upper arm 62 loeinp,- rigidly secured to the shaft (il and the lower arm being it'ree to turn relative thereto. The transmission element* is so positioned on the shat't (31, relative to the pump 35 that the outer end of the lower arm will rest on the pin 56 in the center of the diaphragm.' 0n the proximate sides of the arms, at the outer ends thereof are lateral projections --6-31., which lie in parallel horizontal planes and in Vertical alinement. The lower ond ol the coil spring' 66, fits about a .stud -67- on. the lower arm GQ and the upper end thereol about a pin -68-W which depends from the uppe arm 63, the springir GG serves to space the arms apart and after sustaining a certain amount of compression to transmit motion from the upper to the lower arm.

' The tension of the spring and consequently the power which may he transmitted thereby may he regulated hy means of a nut he operated by any suitable means, that' which l have illustrated. comprising a. cam

59- secured on the shaft 22 in position to impinee upon, and depress the transmission element 60 and through it to the pump. A. wedge shaped member M7%- is adapted to be interposed between the cam 59 and the uppcrfarm 62 of the transmission element, the,` arrangement heine such that the distance through which the arm G3 and consevfluently the entire element and the diaphragm of the pump will he depresswll by the cam, may he varied by adjustingr the wedge to and fro, the broader the portion is which lies between the cam and the arm the greater the distance the diaphragm ol the pump will. he depressed. The wedge pivotally connected at its larger, or rear.J end to an arm 73- which is in turn secured on a shaft fa'fwhich may he extended to any convenient point, and means such as a handle-75- attached thereto for turnthe shalt in order to adjust the wedge 72. The shaft 6l may he extended to a convenient point and provided with means, such as a handle T6, by which it may be turned 'and with it the attached arm 62, whereby through the medium of the spring 6G and loose arm 63, the pump may he operated manually in order to prime the motor to start it. The stem #il of the three way valve -lll may likewise be extended to a convenient point for manipulation.

rl`he operation of the pump may now be understood. The three way valve 40 is turned into position to establish communication between the delivery pipe and the branch The motor is then turned over77 that is, turned manually. As the piston commences its suction stroke the inlet Valve (i is opened, hy 'the action of the cam 13, and a current of air is drawn through the valve 25 and port 1i; as the valve 6 opens the cam 59 actuates the pump to force motive agent through the pipes 39 and l2 and spray the same into the current of air, which is entering through the valve by which'it is taken up forming a combustible mixture which is compressed and exploded in the working chamber of the motor in the usual manner. the usual recurring cycle then insues. 'ihe passage of thc burnt products of combustion through the pipe will raise the temperature thereof to a point which will heat the air passing through the port il and raporize a portion or" the fuel sprayed thereon, this will result in an intimate mixture and consequently increased eliiciency of the motor. lll/hen more power is desired, the valve l0 may be turned to direct the motive agent 'through the brauch pipe to the spray plug 4G, where it is sprayed direct on the highly heated head ol' the piston, with the results that it is instantly and completely vaporized and mixes with the heated air lacing drawn through thc port Ll. ln Fig. 3, a modification of the transmission element is illustrated, wherein, .insteadoi2 having tight and loose arms mounted on the shaft (il with a coil spring interposed between the extremities thereof, resilient strips --80, 81- are secured on a lug 82- extending from a collar-S- which is secured on a bracket "SlrThe regulating wedge 72, being attached to the upright arm -S5- of Va lever mounted in a. bracket --85-. 'lhe arrangement illustrated in Figs. l and 2 is more particularly adapted to autorm'ibile service, the shafts 6l and 'lV-l and the valve stom ill 'being extended to points convenient for manual manipulation, in order to .make adjustments in ordance l'DO l-Sil lll 'with demencia on the motor due to ezigenciee of the reeel.
